Removing list margin

Question

I have an enumerate in which the items are paragraphs (sometimes more then 1 per item) and the paragraphs are indented after the label. How can I change the behaviour so that from the second line of the item, it should start with normal margin (below the label)?

I am using book class.

Answer 1

You can change the \itemindent length to make it equal to \labelwidth+\labelsep, and perhaps also change the \leftamrgin. The enumitem package allows you to do those modifications easily. A little example:

\documentclass{book}
\usepackage{enumitem}
\usepackage{calc}
\usepackage{lipsum}% just to generate some text

\begin{document}

\begin{enumerate}[align=left,labelwidth=1.5em,itemindent=\labelwidth+\labelsep,leftmargin=0.3cm]
  \item \lipsum[1-2]
  \item \lipsum[1]
\end{enumerate}

\end{document}
